It is a primary object of this invention to provide an improved shirthaving an integral collar that can be easily and economicallyfabricated.

A more particular object of the invention is to provide such an improvedshirt that can be fabricated from only one or two sections or panels offabric.

It is another object of the present invention to provide a method forproducing such an improved shirt.

It is yet another object of the present invention to provide such amethod which permits the manufacture of such shirts in both aneconomical and efiicient manner.

Other objects and advantages of the invention will become apparent uponreading the following detailed description and upon reference to thedrawings in which:

FIG. 9 is a perspective view of the finished fabricated shirt with aU-line collar prepared in accordance with the teachings of thisinvention.

While the invention will be described in connection with certainpreferred embodiments, it will be understood that I do not intend tolimit the invention to these particular embodiments. On the contrary, Iintend to cover all altem atives, modifications, and equivalents as maybe included within the spirit and scope of the invention.

The term shirt as used herein is intended to include virtually anygarment worn to cover the upper part of the body and which includes amain body portion, right and left sleeves, a collar and proper openingsfor neck, arms and lower trunk, including garments such as robes,dresses, kimonos and similar articles.

For convenience the term sleeve is used herein throughout to refer to apart of the shirt extending from the armscye. The length of the sleevemay vary to cover part or all of an am, so that the term shirt includesa sleeveless shirt, in which the arrnscye and the sleeve opening are thesame.

Turning now to the drawings, and referring first to FIGS. 1 and 2, thereis shown a shirt 10 made from two panels 11 and 12 referred to as frontand rear panels, respectively.

Each panel 11 and 12 is cut generally in the shape of a human torsobounded by left and right peripheral shoulder boundaries 13b, 13d and13a, 130, left and right sleeve portions 11b, 12b and 11a, 12a boundedby top and bottom peripheral sleeve boundaries Hat-12m, l1ab-l2ab andllbl-lZbl, l1bb-12bb, left and right side portion boundaries 15b, 15dand 15a, 15c, lower trunk opening boundary portions 160 and 16b andfront and back neck or collar opening boundary portions 14a and 14brespectively.

In fabricating the illustrative shirt of FIG. 1, the front and backpanels are attached to one another along the peripheral shoulderboundaries 130, 13c and 13b, 13d, side portion boundaries 15a, 15c and15b, 15d, and top and bottom peripheral sleeve boundaries 1lat-l2at,llab-l2ab and llbr-l2bl, l lbb-lZbbb of sleeve portions 11b, 12b and11a, 12a.

FIGS. 3, 4, 5, illustrate single panels of material which may be foldedand cut to fonn a shirt embodying the invention.

The actual physical attachment of the panels may be effected via sewingmeans, adhesive means or other fastening means. It should be noted thatif a sewing means is employed, very simple stitch operations areinvolved.

In accordance with one important aspect of the invention the neck collarportion of the front panel is cut such that a smooth, full, continuousV-collar-line is formed upon proper inversion and subsequent folding.The front panel may be cut prior or subsequent to interconnecting thefront and rear panels. However in most cases it is preferably cut priorto interconnection.

In order to form a V-line collar it is necessary to properly cut thefront panel of the shirt to be fabricated. To determine how-the frontpanel of the shirt is to be cut, it is first necessary to determine areference point, 0, which likes on an approximate longitudinalcenterline. The longitudinal centerline divides the front panel intoleft and right areas. The front panel is then out along left and rightarea cut lines, each out line being maintained within its respectiveleft and right area and extending from O to points A and A respectively.In a preferred embodiment the left and right area cuts are mirror imagesof one another. Both A and A are equidistant from 0. However 0 cannotlie on a line determined by connecting A and A A is the point at whichthe left peripheral shoulder boundary of the panel intersects the neckopening portion. Similar A is the point at which the right peripheralshoulder boundary of the panel intersects the neck opening portion.

Upon making such cuts a V-shape neck opening portion is formed. Theintegral collar is then formed by inverting the V- shape neck openingportion about inversion points D and D R each lying about equidistantlyfrom 0.

D lies on the left peripheralshoulder boundary. D lies on the rightperipheral shoulder boundaries. D and D are spaced away from A and Arespectively. Upon inverting the V-shape neck opening portion aboutthese points and subsequently folding the resulting collar in place afull, continuous collar is formed.

In a preferred embodiment of my invention inversions points D and Dinclude all points from B to A and from points B to A respectively. Band B are points lying on the left and right peripheral shoulderboundaries respectively.

In order to define the location of the points lying from B to A and B toA it is noted that upon inverting and folding the resulting collarportion about points B and B the sum of the distances between coplanarpoints O-F, and F A is equal to the distance between coplanar points O-Awhile in the unfolded, uninverted position. Similarly when in thefolded, inverted position, the total sum of the distances betweencoplanar points 0-H, and F -A is equal to the distance between coplanarpoints O-A while in the uninverted, unfolded position.

F is a point determined by the intersection of the left peripheralshoulder boundary with a line in the inverted, folded position whichwhen said line is in the uninverted, unfolded position, it lies on aline formed by joining points 0 and A Similarly F is a point determinedby the intersection of the right peripheral shoulder boundary and a linein the inverted, folded position which when said line is in theuninverted, unfolded position, it lies on a line formed by joining O andA Alternatively, cuts may be made on the front panels such that aU-collar-line is produced.

Once again an approximate center line divides the front panel into leftand right areas. A left and a right reference point, O, and 0,;respectively, are determined. Each reference point is equidistant fromthe approximate horizontal centerline. Also, each reference point lieson a line perpendicular to the approximate longitudinal centerline. Thelocation of the perpendicular line is restricted in that it cannot lieon the peripheral neck opening boundary line portion of the rear panel.-

The front panel is out along left and right area cut lines. Each outline is maintained within its respective left and right area and extendsfrom 0,, and O to points A and A respectively. Preferably, such cutlines are mirror images of one another.

A, may be identified by noting that it is a point at which the leftperipheral shoulder boundary intersects the neck opening portion.Similarly A is a point at which the right peripheral shoulder boundaryintersects the neck opening portion. Upon cutting to the respectivepoints, a U-shape collar is formed.

The full continuous built in collar is formed by inverting and foldingthe U-shape neck opening portion about inversion points D and D Point Dlies on the left peripheral shoulder boundary and point D lies on theright peripheral shoulder boundary. D and D are spaced away from A and Arespectively.

The distances between O -D and O -D are about equal.

Preferably the inversion points D and D include all points from 13,, toA and from points B to A respectively. B and B, are points lying on theleft and right peripheral shoulder boundaries respectively.

In order to define the location of the points lying from B, to A andfrom B, to A, it is noted that upon inverting and subsequently foldingthe U-shape neck portion about points B and B the sum of the distancesbetween coplanar points O -F and F -A is equal to the distance betweencoplanar points O -A while in the unfolded, uninverted position.Similarly, when in the folded, inverted position, the sum of thedistances between coplanar points O -F and F r-A is equal to thedistance between coplanar points O -A while in the unfolded, uninvertedposition. I

F L is a point determined by the intersection of the left peripheralshoulder boundary with a line in the inverted, folded position whichwhen said line is in the uninverted unfolded position, it lies on a lineformed by joining O A,

F is determined by the intersection of the right peripheral shoulderboundary with a line in the inverted position which when said line is inthe uninverted unfolded position it lies on a line formed by joining O-A In the most preferred embodiment of this invention the inversionpoints are B and B In order to demonstrate the teachings of my inventionin producing a V-line collar shirt, reference is made to FIGS. 6 and 7.

FIG. 6 shows a front elevation of the shirt to be collared in accordancewith the teachings of this invention. FIG. 7 shows the formed collar ofthe shirt in FIG. 6.

With regard to FIG. 6, the illustrated front panel comprises two sleeveportions 1 and 2 and a main body portion 3. Lines 4-6 and 6-7 representimaginary armscye boundary lines which separate the shoulder portions 8and 9 respectively from the sleeve portion 10 and 11 respectively.Points A and A are the points joining the peripheral left shoulderboundary and the peripheral right shoulder boundary to the neck openingportion 12.

Points A and A, are about equidistant from a reference point 0 whichlies on an approximate longitudinal centerline d, d. Center line d, d,divides the front panel into left and right areas. However, it should benoted that point 0 cannot lie on the'neck opening portion 12.

The front panel is cut along left and right cut lines 14 and 15respectively. Each cut line must be maintained within its respectiveleft and right area. The cut lines extend from reference point 0 topoints A and A The cuts may be of any design but are preferably mirrorimages of one another. The

simplest form for said cut lines would be straight lines formed byjoining reference point 0 and points A and A respective- I ly. Forpurposes of illustrating my invention l have chosen to employ simplestraight cut lines.

In order to form the collar taught by my invention it is necessary toinvert the V-shape neck opening portion about two inversion points D andD each lying on the respective left and right peripheral shoulderboundaries. Also, points D and D may not include points A, or Arespectively. The V- shape neck opening portion which is invertedcomprises the front pattern fabric material surrounding the V neckopening.

In a preferred embodiment of my invention, the inversion points arelimited. In such an embodiment inversion points D and D must include allpoints from B, to A, and from 8,, and A respectively.

Points B and B are points lying on the left and right peripheralshoulder boundaries respectively. Upon inverting and folding the V neckopening portion about inversion points B and B a collar as shown in FIG.7 is produced. The collar as such will be referred to as being in theinverted, folded position. While in this inverted and folded positionthe sum of the straight linear distances between points O-F and F -A alllying within the same plane, is equal to the distance between points O-Awhen the collar is in the uninverted, unfolded position. Similarly thesum of the straight linear distances between points O-F,, and F -A inthe inverted, folded position and lying in the same plane, is equal tothe distance between points 0 and A in the uninverted, unfoldedposition.

In the most preferred embodiment of the invention the inversion pointsare points B and 8,, as defined above. Such is the case for it is onlywith these points that a collar will be produced which is full,continuous, wrinkle and ripple free, and which does not tend to pullupon formation. From an empirical point of view, it can be noted that ifthe sum of the distances between point O-F and F -A in the inverted,folded position is greater than the distance between points O-A in theuninverted, unfolded position and if the sum of the distances betweenpoints O-F and F -A in the inverted, folded position is greater than thedistance between points O-A in the uninverted, unfolded position, thecollar will tend to pull the fabric of the shirt until such distancesare equal since there is an insufficient amount of fabric to extend fromO to A and 0 to A in the inverted folded position. Such an effect willcause a very poor-looking discontinuous, highly wrinkled collar.Similarly, if the distance between points O-F and F A,,, in theinverted, folded position, is less than the distance between points O-Ain the uninverted, unfolded position and if the sum of the distancesbetween points OF and F -A in the inverted folded position is less thanthe distance between points O-A in the uninverted, unfolded position,the collar will tend to ripple since there is an excess amount of fabricbetween O-A and O-A while in the inverted, folded position. A rippledcollar is not however as unattractive as the wrinkled collar.

The two variables affecting the determination of the critical inversionpoints are the length of the neck opening portion of the shirt in theuninverted, unfolded position and the slope of the left and rightshoulder boundaries.

For the purpose of mathematically determining the location of thecritical inversion points, reference is made to FIG. 8 where there isgiven on an X-Y coordinate system the various peripheral boundariesdefining one-half of the symmetrical V- shape collar shown in FIGS. 6and 7.

The reference point 0 is given at the origin. Triangle OAA representsthe front panel collar boundary as originally cut in the uninverted,unfolded position where the distance between A, and A is one-half thelength of the neck opening portion defined as C which would be known fora given shirt. Also, 1 the y coordinate of point A would be known. Line17 represents the peripheral left shoulder boundary upon which the mostpreferred inversion point B, may be found. Triangle OBB represents theinside boundaries of the formed collar. Four-sided figure OGA Frepresents the outside boundaries of the formed collar. It should benoted that point A is given in both the inverted, folded position and inthe uninverted, unfolded position. The distance between points A and Gwill be defined to equal f. The angle 0, which is known for a givenEquation I is derived from the known equation of the line correspondingto the peripheral shoulder boundary for a given shirt which may begenerally written as Equation ll represents the relationship between fand y and x,. It may be derived by noting that the angle 2a is the anglebetween and 6F; Inversion point B must lie on a line passing through 0which bisects angle 211. Therefore the angle between CT; and 6B: is a;the angle between OB andUFZis also a; the angle between m andUBTis(0+a); and the angle between 6A andCFIis (0+2a). Consequently,

Coordinate points x and y of point B, also lie on the line correspondingto the peripheral shoulder boundary and may therefore be written asEquation (d) may be rewritten such that x is a function of y: asfollows:

The following equations then result upon taking the arc tan ofequations(c) and (h):

(i) 6+2a=arc tang-i Multiplying equation (i) by a negative 0.5 andadding the result to equation (j), there results equation II or 0.50=arctan -0.5 are tan 5 f 2/1 Equation (Ill) defines the relationship whichmust exist between points in the inverted and uninverted positionnecessary to obtain a wrinkle-free, ripple-free, full, continuouscollar. It should be noted that all the defined points exist in the sameplane. Equation (III) shows (fi= +F A i.e.,

Since there are three unknowns, i.e., x y, and f and three equations, f,x, and y, may be determined by the simultaneous solution of theequations. Upon determining f, points x: and y may then by determined bythe other functional relationships, i.e., equations (f) and (g).

By following the above mathematical determinations, the location of themost preferred inversion points, B and 3,; may always be established.The mathematical manipulations as shown are not meant to be in any wayrestrictive, since many other combinations of the above relationship maybe used to establish the location of said preferred inversion points.

In constructing the U-shape it should be appreciated that relationshipsidentical to those described for the V-shape collar exist. There is oneimportant qualification to such a statement. The relationships existwith respect to two individual center reference points.

It should also be noted that informing either the V- or U- shape collarthe distance between A, and A i.e., the neck opening portion, ispreferably that of normal shirt neck sizes.

Upon forming a U-shaped collar in accordance with the teachings of myinvention a product illustrated by the perspective view given in FIG. 9results.

By practicing my invention it is possible to fabricate a shirt with anintegral of built in collar from only one or two panels of fabric. I amable to do this as a result of specifically cutting the front panel ofthe shirt to be fabricated in accordance with the teachings of thisinvention.
